1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundAlthough surveillance for hepatocellular carcinoma (HCC) is recommended in high-risk patients, several studies have suggested it is being underutilized in clinical practice. The aim of our study was to quantify utilization rates for HCC surveillance among patients with cirrhosis and summarize patterns of association between utilization rates and patient socio-demographic characteristics. DATA SOURCES: We performed a systematic literature review using the Medline database from January 1990 through March 2011 and a manual search of national meeting abstracts from 2008-2010.

methodsTwo investigators independently extracted data on patient populations, study methods, and results using standardized forms. A pooled surveillance rate with 95% confidence intervals was calculated. Pre-specified subgroup analysis was performed to find correlates of surveillance utilization.

resultsWe identified nine studies that met inclusion criteria. The pooled surveillance rate was 18.4% (95%CI 17.8%-19.0%). Surveillance rates were significantly higher among patients followed in subspecialty gastroenterology clinics compared to those followed in primary care clinics (51.7% vs. 16.9%, p < 0.001). Non-Caucasians and patients of low socioeconomic status had lower surveillance rates than their counterparts.

conclusionsUtilization rates for HCC surveillance are low, although they are significantly higher among patients followed in subspecialty clinics. Current studies fail to determine why HCC surveillance is not being performed. Future efforts should focus on identifying appropriate intervention targets to increase surveillance rates and reduce socio-demographic disparities.
